- Reactivity
- In the presence of water, the methoxy groups of Dynasylan® 1401 hydrolyze to form reactive silanol groups which can bond to a variety of inorganic substrates.
- The organophilic diamino group of Dynasylan® 1401 can react with a suitable polymer.
- The hydrolysis of Dynasylan® 1401 takes place autocatalytically.
- The pH of the hydrolysate is about 10-11. Dynasylan® 1401 may be used with such polymers as phenolic, furan resins and silicones.
- Dynasylan® 1401 can undergo reactions with ketones or ester solvents.
- The silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates or carbamates, respectively.
- Product modifications are possible through co-condensation with polysiloxanes (textile auxiliaries).
